Corrections & clarifications: An earlier version of this story misstated the premise of Senate Bill 1091. That bill started as a measure on Bitcoin, but changed to a measure affecting sales tax collection.

Gov. Doug Ducey signed a bill on Wednesday allowing delivery robots and vetoed one that would have helped cattle ranchers, capping off a session that included multiple business proposals.

It was the last day for the governor to take action or otherwise allow bills to become law without his signature. He took action on 62 bills.

Arizona lawmakers also gave a tax break to coal in the session that ended May 4, but failed to enact protections for home businesses, and eliminate taxes on digital goods and services as they wrapped up the session.

The following are how some of the Legislature's most significant bills that affect businesses in the state turned out.

The bill was one of the last to make it through the Legislature amid turbulent budget discussions and the early-morning adjournment of the session.

Townsend said she was inspired by delivery services she saw during a legislative conference last year in Boston. She researched companies that provide such services in the U.S. and the handful of states that have passed legislation to allow it before crafting her own proposal.

The governor signed the bill Wednesday.

It's a veto for rancher's bill

Ducey vetoed a bill from Rep. David Cook, R-Globe, Wednesday to loosen requirements for archaeology studies for cattle tanks, fences and other "rangeland improvements."

Archaeologists and tribes were concerned amateur archaeologists would inspect archaeological sites, but Cook said the intent is to allow volunteers to conduct the initial survey to see if there are any such sites.

"This administration will continue to be open to addressing the needs and concerns of all the stakeholders who abide by historic preservation laws, and we will eagerly pursue well-defined improvements to those processes," Ducey said in his veto letter.

Cook said he wanted to allow ranchers to simply be able to move the location of proposed projects if someone found they would disturb a historic site and that criticism was off base.

It also was one of the last measures to make it through the Legislature before the session ended.

Tax break for coal approved

This exemption was passed in House Bill 2003 by lawmakers who said it could help find a buyer who will run the plant beyond 2019 — when Salt River Project and the other utilities that own it plan to shut it down.

"This bill is essential to the economic success of the Navajo Nation, the Hopi Tribe, and surrounding communities," Gov. Doug Ducey said in his signing letter.

The power plant near Page is owned by Salt River Project and other utilities, as well as the U.S. Bureau of Reclamation. The utility owners voted to close the plant. SRP has said it will work with any buyer who wants to take over the plant, but none has come forward.

SRP's newly promoted CEO, Mike Hummel, told board members Monday at his first meeting as CEO that the tax break makes the plant slightly more economical, but probably not enough to entice any new buyers.

“It is not in our estimation anywhere near enough to make the plant economical to new buyers,” Hummel said.

Hummel told the board that even if a new buyer for the plant were to come forward today, it would be difficult to negotiate a sale, then negotiate a new lease for the plant with the Navajo Nation, and get a new operating plan approved by the Environmental Protection Agency, before December 2019.

That means that even if a new buyer comes forward, the plant will probably have to shut down that month as planned by SRP before restarting.

Such a shutdown only makes purchasing the plant less economical, Hummel said.

The person who blow-dries your hair will still need a license

The so-called blow-dry bill offered by Scottsdale Republican Rep. Michelle Ugenti-Rita failed to become law. The bill, HB 2011, was highlighted by Gov. Doug Ducey in his state of the state speech and would have lifted the requirement to have a cosmetology license to perform blow-dry and styling services without cutting or coloring hair.

“A word of advice to those bureaucrats, and, yes, even some elected officials, who are resisting this effort: The train is leaving the station. Get on board, or you’re going to get left behind,” Ducey said in his speech.

The train, it appears, won't leave this year.

However, deregulation proponents still took a victory from the legislative session.

Senate Bill 1399 allows barber apprenticeships and was signed by the governor May 2. The apprenticeships can serve in place of barber school, allowing people to learn on the job. It was sponsored by Sen. Steve Smith, R-Maricopa.

House Bill 2333 and Senate Bill 1387 were backed by the conservative Goldwater Institute, Americans for Prosperity and the Free Enterprise club. Some cities opposed the measures because they would limit their ability to regulate businesses when neighbors complain.

Rep. Jeff Weninger, R-Chandler, tried unsuccessfully to move the measure through both chambers.

No tax break for digital goods, services

An effort by Ugenti-Rita to exempt digital goods and services from sales taxes failed. House Bill 2479 would have clarified that certain services, such as using online software to complete tax forms, would not be subject to sales taxes.

The bill also instructs the Department of Health Services director to create statewide rules regarding food preparation and other requirements for food trucks.

"Food truck operators are entrepreneurs who are offering a great product that Arizonans love," Ducey said in his signing statement.

"Creating a level playing field and a uniform standard for Arizona’s food trucks is a commonsense move. This is a step in the right direction to help the rapidly growing food truck industry in Arizona by eliminating the confusion and barriers caused by varying regulations."

Renewable energy measure fails

Tucson Republican Rep. Vince Leach introduced House Concurrent Resolution 2017, which was virtually identical to the initiative that aims to force electric companies to get half their power from renewable sources by 2030.

The other clean-energy ballot measure is backed by a group with ties to wealthy California political activist Tom Steyer. That measure needs about 226,000 signatures from registered voters to make the ballot.

Arizona Public Service Co., the biggest company that would be affected by the measure, is funding an opposition campaign.
